CURB FORM.

My invention relates" generally to an improvement in steel forms for concrete construction work and particularly to those forms used in making concrete curbs. I have shown and will describe my invention in connection with curb forms, but it will be understood that the same is equally adaptable for forms other than curbs.

Heretofore in curb construction wherein metal or wooden forms'are used, the spacer plates which are inserted between the walls of the form at intervals have been of one piece construction, and as in most cases the side walls of the curb form slope inwardly towards the top, it has been necessary either to leave the spacer plates in between the sections of concrete or else remove the side walls of the forms first and then endeavor to pry out the spacer plates. The disadvantages of such arrangement are obvious and it is to provide a spacer plate which may be readily inserted between the side walls of the form after the same have been assembled, and which may be readily removed from between the walls after the concrete has been poured and has partially set. With my improved spacer plates ready insertion and removal thereof is permitted regardless of whether the side walls of the form slope inwardly toward the top or not.

In carrying out this invention, I have pro vided spacer plates in two or more pieces or sections which when placed together, edge to edge, conform to the contour of the side walls of the form and which can be removed from the form sectionally. I also provide novel means for securing the spacer plate sections to the side walls as well as means for securing the sections of the plates together.

Referring now to the drawings wherein like reference numerals indicate like parts Figure 1 is a perspective view partly in section of an assembled curb form illustrating clearly the use of my improved spacer plates. 1

Figure 2 is an outline plan view of one of the spacer plates showing the securing means therefor in two positions.

The side walls of the form are indicated at 1 and as shown are placed end to end and secured together by any suitable securing means 2. As shown clearly in Figure 1, these side walls slope inwardly or towards each other at the top whereby the base is wider than the top. The upper edges of the side walls 1 are provided with notches or recesses 3 at spaced intervals to receive the fingers or hooks 4 at the outside edges of the spacer plates.

These, spacer plates comprise the sections 5 and 6 preferably of flat metal or other 1 suitable material and are placed edge to edge between the side walls 1 to divide the concrete 7 into blocks.

It will be noted with reference to Figure 2 that the spacer plate when assembled has its side edges sloping inwardly toward the top conforming to the space between the side walls 1, the base therefore being wider than the top. With such configuration, it will be clear that it would be impossible to lift the plate as a whole from between the side walls without first displacing such side walls, It is for this reason that the spacing plate is divided into two or more sections, and it will be noted that the dividing line 8 extends from a point centrally of the top downwardly to the base parallel with one edge. With such arrangement, the section '5 with the parallel edges may be lifted out of the form upwardly, thus'making it possible to then withdraw section 6 in the same manner.

-Apertures 9 are providedadjacent the top of'each section for the insertion of a suitable tool or instrument for lifting the sections Means are provided also for holding the sections 5 and 6 together in their assembled relation, comprising notches 10 inthe upper edge of each section and adjacent the dividing edge 8. A fastening element 11 provided with inturned flanges 12 is adapted to fit into the notches 10, thus securing the sections 5 and 6 together.

WVith the parts shown in the position of Figure 1, and it being desired to remove the spacing plates, the operator first removes the fastening element 11, then by inserting a hook or other tool through the aperture 9 in section 5 may pull such section out of the form upwardly and thereafter repeating the operation to section 6, thereby removing the spacer plates without entirely dismantling the form.

Of course, I do'not limit myself to the exact construction shown and described, for changes may be made therein without departing from the scope of my invention as set forth in the appended claims.

I claim I 1. A curb form comprising inwardly sloping side walls, sectional spacing plates between said walls, the edges of said plates conforming to the slope of said walls, said plates being removable by sections from between vthe assembled walls.-
